London: British Prime Minister Theresa May survived a confidence vote by the Conservative Party on Wednesday, but a mutiny by more than a third of her lawmakers indicated parliament was heading towards deadlock over Brexit.

While 200 Conservative lawmakers voted in support of May as leader, 117 dissented, indicating opposition not only from several dozen supporters of a hard Brexit but also from many more pragmatic lawmakers - and signalling that she was no nearer to passing her EU divorce agreement.

It was not the robust affirmation she needed as she heads to Brussels on Thursday to ask the other 27 EU leaders, who have made room for her at a summit, for clarification of the deal to reassure the doubters.
